Civic EG

I looked at my d16z6 tranny rolling in my eg
and I needed to find out about my speed sensor wiring color
so question is that I wanted to know, which wire color that are used for positive?
the reason is that I wanted to hook it up on the switches for some of secret reason.
the color of three wires in my speed sensor plug is black, yellow with blue line on, and white. they are in the order

I am new to this site since I got my first eg at the last few months ago.
thank you for looking!

I also surfed through many website about which wire that are positive and stills couldn't find out, I don't want to buy book for that I wanted to save moneys

It's not a simple on/of. The speed sensor is AC. If I had any indication of what you are planning, I might be able to tell you if it's even possible.

I forgot to post it up, the real reason that I wanted to know which are a positive wire
